(Cl. 28-21) The invention relates to a method and means for reeling of yarns or threads whereby the spun or twisted yarn wound upon bobbins and the like is to be wound to simple hanks or hanks which are divided into bunches in order that the yarn will be treated uniformly by the colouring uid during the following dyeing process, in particular that the yarn may be moved at will in the colouring iiuid and that it can be dried uniformly after dyeing.

The circumferential length of the hanks is made between l40 to 80 corresponding to the circumference of the reel drums. The hanks are manufactured in weightsV between 25-500 grammes. They may be divided into several, Afor instance live bunches and the yarn windings are loosely bound at least at two points of their circumferenceY by means of crossing threads in order to avoid entanglement of the diverse windings or of the bunches when the bunches are moved in the colouring uid or during further treatment and manipulation. The known reel drums usually form an hexagonal prism consisting of metal crosses and corresponding longitudinal bars.

Such a reel drum has a length of about 140 to 160". It is rotatably mounted only on the two journals at the ends of its shaft. the reel drum a thread-guiding bar is moved to and fro on which are mounted the equally spaced thread guides. The yarn wound up in the form of bobbins or the like is drawn through a thread guide to the reel drum where it is clamped to a longitudinal bar by means of clamping springs. The reel drum, upon rotation, will be wound round with hanks whereby between the bunches of the hanks small spaces are left.

After this the reel drum will be stopped and the hanks or bunches will be bound with crossing binding threads by hand and the different hanks will be separated from the bobbins or the like by cutting the running yarn threads.l By displacing of some longitudinal bars the circumference of the reel drum will be reduced and the operator now draws the loosely hanging hanks with his arm from the remaining longitudinal bars and, what is more, along the whole length of the reel drum up to the discharge wheel, putting them in a recess of the discharge wheel, turning it by hand about 360 in order to free the finished hanks from the reel drum. w

After applying new yarn the reel drum can be rotated again in order to produce a new set of hanks, 'Ifhe duration of the idleness of the reel drum or the machine, respectively, is essentially greater than the duration of its rotation, so that the work done by such a reel is comparatively small and the costs Vof production are comparatively high in consequence of the necessity of the service by hand of binding the hanks or bunches, separating the hanks from the bobbins, taking ol the hanks, applying the threads for av new set of hanks, sticking up new bobbins and the like.

The method of reeling, according to the invention, is performed in such a manner that the yarn is wound up continuously on the Aone end of a reel Parallely to the longitudinal bars ofdrum in the form of hanks spaced from each other and vthe hanks are shifted onto the other end whereby they are bound'into separate bunches by binding means and then theyf are separated yfrom each other and the nished-hanks will be discharged at the other end of the reel drum.

The new reeling device, accordingly, consists ofa reel drum and a winding up device by which the yarn is` wound up continuously in the form Vof hanks and bunches separated from each other on the one end `of the`re'el drum, a feeding device, shifting the wound up hanks or bunches onto the other end, discharging them after the' hanks are separated from each other by a severing device.v

By these measures it is attained that the reel drum can be continuously rotated without idleness and all` manipulations by hand hitherto absolutely necessary .for

binding, separating, taking off the hanks, applyingagain the threads and so on fall away. The effect on production of such a device is a multiple of that of the hitherto reels and substantial salary being saved.

The transport of the wound hanks or bunches from' the one end of the reel drum to the other one may be` performed by dierent means, for instance by bars which are provided with pins, or by wheels or bands engaging the hanks. During winding of each bunch the reel drum may be shifted to and fro by the width of a bunch.

According to the invention,

bunches, suitably shifted by one width of a bunch enlarged by the space between two adjacent bunches byj means of endless supporting bands located inthe reel drum. The nished bunches then remain-in'rest `until the next bunch is wound.

The actuating of the supporting bands is elected by,

means of an electro-magnet which is connected xwith idler rollers of the supporting bands through a rack and.

a Ifree wheel gear mechanism .as will be more fully eX- plained later.

The winding up end of the reel drum of circularrs'ection changes into an oblong section formed by gliding( plates or gliding ribs. Longitudinal spaces are arranged between the gliding plates in which the devices fori binding and the hankwise separation of the bunchesare located in pairs in one or more than the reel. The thread guide ofthe reel drum `for 'conveying the yarn tothe reel drum is axiallyl shiftable. It

may be further rockable in an axial plane; The thread 1 guide is, as is known with winders for yarn bundles,

located in a rotor rotatably mounted in a stator. 4The rotor serves as a bearing for the reel drum. Means ,arev .Y provided for by which the reel drum will be retained-.-

stationary with respect to the stator. K Reel drum and stator are connected with each other by a planet gear in which the planet ring of the reel drum and a gear ring of the stator. planet wheels are rotatably mounted in the rotor.

the two gear rings so that the reel drum is held vunrotatably with respect to the stator.

The actuation of the devices located in the reel drum is effected either by electro-magnetic means or mechanically dependently on the relative movement betweenfthe,I

rotor and the reel drum.

For binding up the bunches crossing binding means are used nunning in and outside of the bunches and being fed according to the shifting of the bunches., These binding means are connected with each other between adthe adjacent bunches at The connection of form of threads or after each winding of a- `bunch this will be, together with the previously wound one axial planes of wheels engage a gear The.. Theirratio of gear corresponds to the ratio of the diameter of consists in part or wholly of weldable plastic strips which are welded together between the bunches by pressing them together by means of stamps which may be heated. In order to avoid' the forming of drops of colouring lluid on such means'consisting of plastic after the dyeing whereby blurs in the yarn may arise, the means consist of'loosely woven strips of tine plastic threads, which are temporarily stitfened for their manipulation and the binding by a stiffening means which dissolves in the colouring uid. A binding and a severing device is provided for each of two, four or more binding means distributed round the circumference of the reel drum at distinct points which are supported by projecting arms of the stator, by which the bunches are bound and the hanks are severed from each other, respectively.

At the separating point of one of the bindings the connecting thread between neighbouring hanks too, is to be cut. Particular devices are necessary lfor this purpose by which the said connecting thread is brought into the reach of the severing device.

f In order to secure the beginning and the end of the yarn of each hank the connecting thread between two adjacent hanks will be secured to the binding means for instance by welding or by knotting in such a way that upon cutting of the corresponding binding point the connecting thread will be retained securely at the severed ends of the binding means. Particular devices are necessary to guide the connecting thread through the cutting spot of the binding means in question.

Further features of the invention will be apparent from the following description of an embodiment of the invention which is described simply by way of example, with reference to the accompanying diagrammatic drawings, in which: i

Fig. 9 is atop elevation ofthe reel drum.

The reel comprises a stator 1 (Figs. 1 and 2) which is formed as a casing for a reel drum 2 being held unrotatably, and a rotor 3 arranged between the stator and the reel drum. The rotor 3 is rotatably mounted in the stator I by means of two ball bearings 4 (Fig. 2). In the rotor the reel dnum 2 is rotatably mounted at its bearing end by means of ball-bearings 6. On the rotor 3 a thread guide 7 is mounted. The thread 8 is brought to the thread guide from a bobbin 9 or the like which is mounted on a supporting member connected with the stator 1. The thread 8 runs through a bore 11 of the thread guide 7. On rotation of the rotor 3 the thread is wound up on the winding zone 12 of the reel drum. 2. After each winding up of a bunch 13 a shifting of all wound up bunches takes place towards the discharge end 14 of the reel dnum.

For holding the reel drum 2 stationary with respect to the stator 1, diierent means may be used, for instance magnetic forces. Preferably said holding of the reel drum 2 is brought about mechanically by a planet wheel gear which, in the embodiment represented in F ig. 2, consists of a shaft 15 mounted rotatably on the rotor in radial direction which at its inner end engages a bevel gear ring 17 of the reel drum by means of a bevel gear 16, and at its outer end engages a bevel gear ring 19 of the stator by means of a bevel gear 18.

When the ratio of the diameters of the bevel gears 16 and 18 is equal to the ratio of the diameters of the bevel gear rings 17 and 19 the bevel gears roll on their bevel gear rings with the same angular velocity so that a mutual rotation between the stator and the reel drum does not take place and the latter thereby will be held stationary with respect to the stator. For the same purpose other planet wheel gears, for instance, spur gears with the same ratio of gear may be used.

The drive of the rotor 3 is introduced through a pulley 21 which is mounted on the circumference of the rotor 3 between the ball bearings 4 by means of a wedgeshaped belt 22 (Fig. l) and a motor 23 which is mounted in or on the stator 1.

At the winding up zone, the reel drum 2 has a circular cross section so that upon uniform rotation of the drum the velocity of the thread always remains the same and by this way the highest winding up velocity can be attained.

Towards the discharge end 14 the circular cross section changes into an oblong cross section, care being taken that the length ot the circumference of the drum remains the same in all radial sections in order to hold the bunches stretched during their wandering along the reel drum. In order to facilitate the movement of the bunches to- 'wards the discharge end the circumferential length of the drum can be decreased towards the discharge end by |a little amount.

As is apparent from Fig. 3 the drum is formed in the oblong part of its section by longitudinal gliding plates 24 which are secured to the bearing head 5 of the drum and stiiened to each other by cross arms 25. Between the gliding plates free spaces 26 (Fig. 3) are formed which serve for the location of the means described below for binding, cutting and transporting of the bunches towards the discharge end 14.

The movement of the bunches towards the discharge end is performed by supporting bands 27 (Fig. 2), which run over rollers 28, limiting with their outer parts thel circumference of the drum as is apparent from Fig. 2, in such a way, that in the winding zone 12 of the real drum the bunches are wound directly on the supporting bands.

When the supporting bands are moved in the direction of the arrow 29 (Fig. 2) all of the bunches are taken towards the discharge end 14. The drive of the supporting bands is performed step by step corresponding to the width of the bunches and the width of the space between neighbouring bunches. To this end a gear may be used which is arranged in the bearing end 5 of the drum and which will be actuated by the rotation of the rotor 3. In the embodiment represented in Fig. 2 the drive of the supporting bands 27 will be brought about by an electromagnet 31 (Fig. 2) which is located in the reel drum, the solenoid of which shifts a rack 32 being in mesh with gear wheels 33, which turn supporting rollers 28 journalled in the bearing head 5 of the reel drum over a free wheel gear 34. During the return movement of the gear rack 32 actuated by spring force these parts remain unintluenced by virtue of the free wheel gear. The energization of the electro-magnet 31 in appropriate moments every time a new bunch has been wound up may be effected in any of the numerous manners which will be apparent to those skilled in the art. For instance the magnet may be connected to a source of voltage through appropriate switch means by hand or automatically by cam means dependently on the rotation of the rotor in lsuch a manner that after a certain number of revolutions of the rotor the switch means will be actuated. For instance, the ring 37 (Fig. 2) may be connected by means of toothed wheels with a member rotatably mounted in vthe reel drum 2, in such a way, that it closes the circuit of the electro-magnet 31 each time when theV rotor 3 has performed a certain number of revolutions.

Upon the winding up of each bunch or bank the thread to Ibe wound up must be moved to and fro within the bunch width or hank width in the direction of the drum axis. This may be enabled by a corresponding to and fro movement of the supporting bands 27 or the whole reel drum respectively. With the represented embodiment (Fig. 2), for this purpose, the thread guide 7 is mounted longitudinally movably in the rotor 3. It engages, by means of a projection 35, a cam notch 36 of a ring 37 which is rotatably mounted about the bearing head 5 of the reel drum. The ring 37 is provided at the inside with a gear ring 38 engaging a gear wheel 39 rotatably mounted in a bore 41 of the bearing head 5 and the shaft journal of which being connected for rotation with the rotor 3 in suitable manner. This connection is performed in such a manner that an extension 40 of the shaft 15 engages a slot 43 of the shaft of the gear wheel 39. When the rotor is rotated the gear wheel 39 will be rotated with it whereby owing to the cam notch 36 the thread guide 7 will be moved to and fro.

The automatic binding of the bunches 13 will be effected by devices 44 (Fig. 3) which are arranged at the spaces 26 between the gliding plates 24 of the circumference of the reel drum. At least two of such oppositely arranged devices 44 are to be provided for. It is however advantageous to use more than two devices in order to avoid the entanglement of the windings of the bunches or hanks, respectively, as far as possible. Fig. 3 shows an arrangement with which in the middle portion of the broad side and in the middle portion of the narrow-side of the reeldrum binding devices are provided, taken altogether, four binding devices.

With these binding devices, appropriately, an inner and an outer binding member in the form of a thread, a strip or the like is used, which may be stitched or knotted with each other in the manner of the lower and upper yarn of a sewing machine. The inner binding members 45 (Fig. 2) run from supply drums 46 mounted in the reel drum and are directed to the inner circumference of the bunches by means of direction changing rollers 47. The outer binding members 48 run from supply drums 42 which are mounted on projecting arms 51 of the. stator lvextending along a part of the length of the reel drum.

Here, direction changing rollers 47 are not necessary.V

The direction changing rollers 47 for the inside binding members enable the supply drums 46 to be arranged at the front end of the reel drum, in order that they can be more easily filled up or changed.

With the represented embodiment of the invention the lower and upper binding members are connected between the bunches by welding. To this end they consist wholly or in part of Ia cold or Warm Weldable plastic and the welding will be performed by pressing stamps, which may be heated in an appropriate manner. The binding members 45, 48 have the form of narrow strips 52 (Fig. 7). In order to avoid a forming or a sticking to of drops of the colouring uid upon or after the dyeing they are, as shown in Figs. 4 and 5, woven loosely of thin plastic threads. This loose web will be provided with a stiifening means, for instance with starch or the like, which on bringing the bound hanks into the colouring fluid dissolves in same so that the formation of drops after taking the hanks out of the colouring tluid cannot take place.

By the stitening it is attained that the binding members can be precisely and surely fed and manipulated in the reel devices.

The welding is brought about by means of stamps 53 (Fig. 2) mounted on the projecting arms 51, which stamps cooperate with counter members 54 in the reel drum and are actuated in the suitable moment mechanicwy or electro-magnetically. The stamps may be electrically heated. After each step of movement of the supporting hands by means of the rack 32, pressing ofV the stamps 53 onto the counter members 54 takes place between two Vadjacelylt bunches whereby` the inner bind.

ing members 45 are welded with the outer binding memthe following movement of the supporting bandsV the severed hanks will be automatically discharged.

In addition to the binding strip 52 in one of the cutting places for the hanks the connecting thread 57 (Fig. 7) between the two adjacent bunches must be cut. When the cutting device for this purpose is located at a distinct place on the circumference of the reel drum it is -to be taken care that the connecting thread has attained this place in the moment of the knife movement. Further, it is desirable to secure Ithe cut ends of the connecting thread to their hanks in a suitable manner in order that they do not loosely hang at their hanks. The last mentioned problem is solved in that the connecting threadis.

connected with one of the binding strips at the connecting or welding spot disposed as place for the separation of the binding strip between consecutive hanks. In particular, the connecting thread will be welded in between the two binding members 45, 48 so that upon the severing of the welding spot the ends of the connecting thread remain in the ends of the binding strip made by the cut. This proceeding can be brought about in a different manner.

With the embodiment represented in Figs. 2, 6 and 7 the two supporting bands 27 (Fig. 7) moving adjacent the concerning binding strip 52 are provided with projecting pins 58, 59 spaced from each other according to the width of the hanks. The oppositely arranged pins 58, 59 have a distance, seen in the direction of movement of the bands (arrow 29), from each other corresponding to the space between two bunches 13. Upon the winding up of the yarn on the reel drum according to the arrow 62 (Fig. 7) by means of the yarn guide the thread must at first arrive before the pin 58 of the one supporting band and then behind the pin 59 of the other supporting band, so that the connecting thread 57 is located precisely at the spot 63 disposed for the cutting of the binding strip. In order to correspondingly guide the connecting thread 57 a movable needle-hook 64 (Fig. 2) is provided in the reach of the Winding up zone of the reel drum on the upper projecting arm 51. The needle-hook 64 will be moved by an electro-magnet 65 in such manner that it seizes the thread immeriately after the passing of the thread guide 7 at the pin 58, whereby the thread in the sense of the arrow 29 (Fig. 7) will be put before the pin 58. After seizing the thread will be returned oppositely to the direction of movement 29 so far that during the further movement of the thread guide it arrives behind the pin 59.

As -is obvious by these means, the connecting thread is directed in such a manner that it crosses the spot 63 of the corresponding binding strip 52 disposed'for the cutting separation of the hanks from each other. In

this position the connecting thread 57 will be carried.

in the described manner by the supporting bands in the direction of the arrow 29 up to the appertaining welding stamps 53 for ythis binding strip 52 and will be welded and -then carried up to the corresponding cutting device 55, 56 (Fig. 2) which is arranged in the direction of the line 66 (Fig. 7), so that upon cutting the correspondl from the thread guide 7 will be seized after passing the thread guide 7 by a two pronged catching lfork 67 in the manner shown in Fig. 8 whereby the thread 8 will be formed to a loop having a cross piece S7 (Fig. 8) representing the connecting thread later to be cut. The catching -fork 67 is shiftably mounted on one of `the projecting arms 51 and is influenced by an electro-magnet 68 (Fig. 1) which moves yit according to the wandering of the wound up bunches in the direction of the arrow 29 (Fig, 7). Thereby the cross piece S7 (Fig. 2) will be brought between the arriving inner and outer binding members 45, 48 and between the appertaining welding stamps 53, 54 (Fig. 2). By the latter the connecting thread 57 will be welded in between the two binding members 45, 48. Thereafter the catching fork 67 can be freed by return movement 'from the thread 8 (Fig. 9). If then upon the further movement of the bunches -in the direction of lthe arrow 29 the corresponding welding spot reaches the appertaining cutting device 55 (Fig. 9) it will be likewise cut in the manner indicated in Fig. 7, so that also the connecting thread 57 is cut, the ends of which will remain fixed to the ends of the cut up binding strip 52.

f The movements of the needle-hook 64 or the catchingfork 67, respectively, which are necessary in order to take up the arriving yarn -thread 8 can be avoided in that the thread guide 7, as indicated in Fig. 9, is mounted rockably about an axis 69 and is influenced by an electromagnet 71. Upon passing the needle-hook or the catching fork, respectively, the thread guide 7 will be rocked counterclockwise whereby the thread is put on the needlehook or the catching fork 67, respectively. The needlehook or the catching-fork, respectively, then only has still the task to move the thread forwards or back in the described manner.
